For best results, when wax is melted, place candy thermometer in wax and bring to wax manufacturer's recommended temperature for adding fragrance. Remove from heat and stir in 1 tablespoon vanilla extract, 1 tablespoon ground cinnamon and ½ teaspoon ground cloves for about every 2 cups of melted wax.
Candle wax is not burning evenly all of the way down: Possible Causes: Wick may not be centered, wick may be too small, your wax may be too hard (too high of a melt point). Candle may be in a draft, under a fan, near a vent. Try using a softer, lower melt point wax or try using a larger wick.
